About Promo Radar
Promo Radar helps you answer a simple question before any Amazon purchase: should I buy now, or wait for a better price?
What you get
Paste any Amazon product link and we show you how today's price compares to the recent 90-day range. You get a clear recommendation — Buy, Hold, or Wait — so you can decide with more confidence and less guessing.
How it works
We pull historical pricing data from a third-party marketplace data provider, compare the current price against its recent baseline, and surface the result in a way that is easy to read. We also highlight active coupons and deals when they exist.
What we do not do
We do not predict future prices. We do not guarantee savings. Our recommendations are based on historical patterns and should be one input in your decision, not the only one. Amazon prices change frequently and may differ from what we display.
Where it works
Promo Radar supports 11 Amazon marketplaces: US, UK, Germany, France, Italy, Spain, Japan, Canada, Mexico, Brazil, and India.
